Researchers developed allometric equations to estimate aboveground biomass in agricultural landscapes in Western Kenya. They found that using tree diameter at breast height alone can accurately predict aboveground biomass with over 95% accuracy. Existing equations overestimated biomass due to errors in estimating smaller trees and larger trees. The study recommends using tree diameter as the basis for assessing tree biomass in agricultural mosaics in Western Kenya. These equations are a valuable tool for estimating carbon sequestration potential in agricultural landscapes and scaling biomass estimates for entire areas.
